.application filed August 31, y1925.' serial No; 53,450.

Our invention relates to liquid dispensing apparatus, vand particularly to improvements in apparatus of this character designed for the retail dispensing of'soft drinks in restaurants, soft drink parlors, fairs, dance halls, etc. The objects of the invention are to provide apparatus of this character which may be economically built, easily and accurately7 operated, which will withstand rapid and hard usage, which shall dispense at each operation substantially the same amount of liquid, in which the liquid' may be kept cool andrefreshing, and which shall be satisfactorily sanitary.

rlhe annexed drawings and the following description set forth in detail certain means embodying our invention, such means constituting, however, but one of the various forms in which the principle of the invention may be applied.

ln said annexed drawings:

Figure 1 represents a top plan view of our improved liquid-dispensing apparatus;

Figure 2 represents a vertical sectiony taken in the plane indicated by the line' II-L Figure 1, and showing, in full lines, the dispensing bucket and connected parts in normal position, and, in dot-and-dash lines. showing these elements in the positions which they severally occupy when the bucket has been moved substantially halfway upwardly to its dumping position. An open position of a door covering a. liquid filling opening` is also shown in dot-anddash lines in this figure. A

Figure 3 represents a plan'section, taken in the glane indicated'by the line III-111, Figure v2; y

Figure l represents a view similar to Figure 2 in which the ydispensing bucket yand the parts operating therewith are shown in dumping position;

Figure 5 represents a vertical cross section, taken in the plane` indicated by the line V-V, Figure 2;

Figure 6 represents a front elevation, with the bucket and connected parts in nor.- :mailv position;

Figure 7 represents a fragmentary front elevation, with the bucket and connected parts in dumping position;

Figure 8 represents a side elevation of the crank end ofthe connecting rod; two positions of certain means for ylocking` the joint between the connecting` rod andthe bucket support are also shown in this view, and y Figure 9 represents across section, taken in the planev indicated by the line IXIX, Figure S.'

Referring` which the saine ordinals indicate the same res aective :elements in the several views, we

' indicate an insulated casing'or frame by the ordinal 1 having a top 2 provided with covers 3 for openings through which ice may be vdumped around a liquid receptacle 18 adapted-to hold the liquid which shall be dispensed, said receptacle being mounted inV the frame 1- by means of legs l0 and brackets 26"'and being provided with a hinged door covering an opening through whichv the liquid to be dispensed may be poured tol fill the receptacle 18.v A portion 2 of the cover is eXtended'upwa-rdly from the `frame 1 and upon the front side lof the frame adjacently below the forward edge of this top 'portion 2 is formed a casing opening` 5 for which there is a hinged cover 6. This cover '6 also formsa door covering a. discharge opening from the liquid receptacle 18. A bracket `7 is secured to the under side of the cover 6, and pivoted by means of a pin-S to 'this bracket 7 is the forward end of a connecting rod 9, hereinafter more fully described. v

. The door 6 supports a register 10 hingedly connected with one'end of a link 11 whose other end is pivoted in the top of a vertical post 12 mounted upon the cover member 2". A standard 14 mounted in a -boss lfformed'upon thecover 2 supports an electrically illuminated sign 15 formed with a light socket 39. y The standard 14 alsoextends into a boss'16 formed upon the underside of the cover member 2 and rests upon a shock absorbing plug 17 secured in the boss 16.

The liquid .receptacle 18 is formed with a well 19 in the bottom of which the bucket or scoop normally rests, as plainly shown invFigui-e 5. Laterally extending bosses 21 formed upon the two sides of the receptacle 18 form bearings for a shaft 22 held Vin position by pins 24, this shaft intersecting the main casing 1 at one side and being formed with an operating handle 23. A hub mein-v ber 41 of a depending arm 30 is pinned to the shaft 22 and forinsza support for a bucket 27 as shown in'F-igure 5. Thisbucket tothe annexed drawings iny llG 27 is formed. with a pair of opposed laterally extending' trunnions 3l journalled 1n bear'- ings 'formed adjacent the bottom end of the arm 30 and in an angular detachable arm 32 secured adjacent its upper end by bolts 33 to the depending arm 30, as shown in Figure 5. The construction of the bucket 27 (is shown in Figure 2 and it is evident that the capacity of the bucket is determined by the position and character of the lillin'g hole 29. By means of the detachable angular arm 32, forming one of .the supports for the bucket 27 buckets having diil'erent capacities by reason of the different positions and characters of the filling holes 29 can be interchangeably used 1n the same supports 30 and 32 by means of taking o'l" the arm 32, removing` a bucket of one capacity and' replacing it with .a bucket of another capacity. Extended laterally from the arm 3() and adjacent the upper end of the latter is a short krod section 34 formed with a peripheral groove 35. The connecting rod 9 is hook-shaped at its rear end, as

`plainly shown by the ordinal 43, Figure 8,

and this hooked end is adapted to engage the groove 35 of the rod section 34 thereby to connect the rod 9 to the depending bucket support 30. In order that the joint between the rod 9 and the rod section 34 may be effectively locked and yet allow for the ready attachment and removal of the rod 9, we provide a sliding key 36, plainly shown in Figures 8 and 9, which can be readily moved upon the rod 9 to the position shown in dot-and-dash lines, Figure 8, for allowing the removal of the rod 9 from the groove 35, and which can be moved into the full line position, shown in Figure 8, to allou7 for the locking of the rod 9 and the rod section 34. Adjacent the lower end of the discharge opening 5 a plate 25, of the design plainly shown in Figure 3,'is secured to the casing l by brackets 20, this plate 25 being formed with an upwardly extending flange 26 forming an .edge upon which the bucket 27 is tilted, when the bucket is raised to the position plainly shown in Figure 4. The weight of the bucket 27 and the door 6 and the connected members will move these elements, under the influence of gravity, to the respective positions shown in full lines in Figure 2. The distance from the :flange 26 to the rod section .34 is such, compared to the length of the depending support 30 and its points of attachment 3l to the bucket 27, that when the bucket 27 is raised to a position adjacent the discharge opening 5, the rear end of the bucket will be lifted above the flange 26 to discharge the contained liquid through the mouth 28, as plainly shown in Figure 4.

Means are plainly shown in Figures 2 and 5 providing` for the hinging of the door 4 covering` the receptacle iller opening and for the iixing of said door 4 vertically in an open position. Means 37 are shown in Figures l and 3 providing for the draining of' the iceV compartment 44.

It is apparent from the lforegoing description and the accompanying drawings that the actuation of the operating handle 23 forwardly from the position shown in Figure 5 will li'tthe bucket 27 from the position shown in full lines in Figure 2 to the position shown in dot-and-dash lines in said Figure 2, the discharge end of the bucket travelling along the guide 45 formed by the lower trough shaped portion of the receptacle 18, and then lift the bucket to the dumping position shown in Figure 4, the cover 6 having been lifted at the same time by the connecting rod 9 to the position shown in Figure 4. In the meantime the pivoted link ll acting upon the arm l0 of the register l0 has recorded the operation. Either a release of the handle 23 or a movement of the same in the opposite direction will cause the sev-eral elements to reassume their normal positions shown in Figure 2.

What we claim is:

l. In liquid-dispensing apparatus, the combination of a liquid receptacle formed with a discharge opening; for said opening; a bucket; a movable'support for said bucket; a link pivotally connected to said support and pivotally connected to said door; means for tilting' the bucket to discharge through said opening; and means for actuating said bucket support to lift the bucket into juxtaposition with said tilting means and to open the discharge-opening` door. i
